2013 Bad year for Global warming

Notice anything?

The lack of any links to sources? Graphs of the Northern Hemisphere being described three times as 'global'

I'm sure you verified the accuracy of the comparison, rather than just uncritically cutting and pasting from the website of climate comedian Stephen Goddard.

Going back to anomalies and baselines, the second graph is from the Hadley Centre who use the period 1961-1990 as their baseline. As the first graph is from a US NAS report dated 1975, they cannot possibly have the same baseline so once again: comparing apples & oranges.

You also have to know what data are being plotted, what smoothing was done, etc. Do you know what data are actually being plotted in graph 1? I do, but I didn't post the graph, or make any accusations of data fiddling, and its too near Christmas to be spoon-feeding trolling muppets. Hint: Budyko (1968).

Be sure to share the answer if and when you find it (yeah, I know, but I'm an optimist at heart). Another hint: I wouldn't rely on Goddard, he lost the gig at WUWT for being publicly and serially wrong, now that takes some doing.

Have you verified the accuracy of the GISS temperature which differs pretty siginificantly from the other data sets

US NAS report dated 1975, they cannot possibly have the same baseline so once again

Explain why 1880 has the same negative anomaly as the modern graph then, and explain why in 1975 the temperature had dropped to the same level it was in 1900....try using simple arithmetic skills to spot the inconsistency. (hint if you look in the mirror you might be able to see a nose).

Well, if you go back as far as 1880, the uncertainties become pretty large






so not that surprising that there are discrepencies between datasets that far back. Human influencies on the climate only really became significant in the first half of the 20th Century and only became dominant after about 1950, so this is all a bit academic....

But c'mon Mr Bates, why so coy? So we know what we're discussing, what is the source of the data in your first graph? Surely you know ?
